Question

Determine el perímetro y área De un semicírculo e radio 0.5 m.

Answer 1

Respuesta:

     $P = 1.57m$          ;            $A = 0.3925m^{2}$

Explicación paso a paso:

$Radio: r = 0.5m$

$\pi = 3.14$

Perímetro: P = ?

$P = \frac{2\pi r}{2} = \pi r = \pi (0.5m ) = (3.14)(0.5m)$

$P = 1.57m$

$Area: A = ?$

$A = \frac{\pi r^{2} }{2} = \frac{\pi (0.5m)^{2} }{2} = \frac{(3.14)(0.25m^{2} )}{2}$

$A = \frac{0.785m^{2} }{2}$

$A = 0.3925m^{2}$
